Otto Von Bismarck - His Policies of German Unification

Otto von Bismarck or Otto Eduard Leopold, Prince von Bismarck,

could flare up and involve Germany. In 1873 he embraced a pacific
foreign policy when he negotiated the Dreikaiserbund (Three Emperors'
League) with Russia and Austria-Hungary. But the alliance did not
survive the Russo-Turkish War of 1877. When the Austrians and British
threatened war over a Carthaginian peace imposed on Turkey by the
Russian victors, Bismarck called for a peace congress in Berlin. The
German chancellor succeeded in getting the Russians to moderate their
gains, and peace was preserved.
But a European conflagration had barely been averted. Soon
after the conference, Bismarck negotiated a defensive alliance with
Austria-Hungary, which remained in effect through World War I.
Although in the mid-1860s he had rejected such an alliance as harmful,
